Hello...

I was bored so I went to download.com to look for software.
I picked this category: Optimizers & Diagnostics.
Then I sorted by votes.
Now I checked some programs...
The CNET reviews were giving 5 and there were many good comments but also some bad.
The bad comments were saying that program A deleted explorer.exe on uninstallation and that program B "killed" their registry when optimizing it.

The good comments were saying that program A doubled their PC speed and that program B made their registry file smaller.

Here's some programs for example:

Here's the complete list:

Do you trust these programs?
Do you think that they will scr*w my computer?
